Hi,
I recently bought a prime 4 over the weekend and decided to buy a internal drive to store music. I have bought a Seagate Barracuda 2.5" Sata 1TB (HDD) and installed into the bay under the unit. However when I turn the prime 4 on it does not recognise the drive. I tried hooking up the laptop and putting prime into controller mode but still no drive is shown. Did I do something wrong?
About to return drive to shop. Can I not just use an external hd instead and format it using exfat? and if so, does it need to be powered by mains or can the prime power the device?
Oh, I just assumed I could format while the drive was mounted into the prime 4 by connecting the laptop into controller mode. Problem is the laptop does not recognise any drive installed, so I cant format it. I have just ordered a Sata to usb cable so I can hook it up to the laptop and see whats happening.
On Apple thatâs the way it works. On windows pcâs you will first have to format the drive separately from the P4, before you can put it into the P4 and put your music on it through Engine prime (when connected via usb and P4 in controller mode). Iâm sure it will work once you have formatted the drive. Best is to use ex-FAT.
100% agree - I couldnât format the harddrive with my PC but as soon as I hooked the Prime4 to my Mac. It worked no problem. Once formatted it worked perfectly with my PC or Mac.
This does not appear to be correct⊠I am experiencing the exact problem as others above, where a raw drive does not show up to a Windows computer when in controller mode (formatted USB sticks do) on v1.3.3. Also, there is no easy way to even verify the drive is present/seen by the P4 unit (they should add some sort of diagnostic view to Utilities or something so we can verify what drives/devices are âseenâ by the unit at different abstraction layers (hardware, filesystem, etc.).
Thanks for your reply; I now understand the point youâre trying to make but I think a lot of folks may not know all the Winternals necessary. For folks having trouble:
Disks (of any sort) must have a partition table mapping the raw geometry of a disk to logical drives addressable by computer operating systems. This is generally referred to as âinitializingâ the disk.
Once partition(s) exist, the computer can then âformatâ it with a specific filesystem type (we want âextended FATâ or âexFATâ) so that the disk is usable.
Most raw disks (straight from the manufacturer) do not have a partition table defined (âunitializedâ), leaving that to the computer/end user (there are a few different partition table types)
The Prime 4 apparently does not have the capability to create or manipulate partition tables, which means you need to do so when attached to your computer while the controller is in Controller mode
The way Windows and Mac handle raw disks (that need a partition table) is very different.
Macintosh handles initialization and formatting the disk in a single operation by exposing the raw (uninitialized) disk once itâs plugged in.
Windows only displays initialized disks under My Computer. To see uninitialized disks (and to initialize them) you must do so through Disk Management.
So, for Windows users who canât see an internal SSD on the P4:
Start Menu
Type âpartitionâ
Click âCreate and format hard disk partitionsâ
Look through the list at the top (or bottom) for a disk that has no file system and matches the capacity of the size you put into the controller.
Right Click -> Initialize Disk
Pick MBR and OK
Format the disk (exFAT) and assign a drive letter if needed (all in right click menu)
Awesome write up! It will probably be easier for people to find if you include something in the subject line about âfor Windowsâ (as I suspect this is how people will be searching for this info).
Also, Denon friends, please consider:
Adding the above to official docs
Add init disk capability to P4 onboard capabilities (GPT support would be nice too)
Add some sort of hardware / disk info or explorer capability to utilities to help users figure out the problem before having to track down this forum thread.
Hello, I am not sure whether you have solved your problem, but I think you can try to uninstall the Hard Drive and then Reassign the drive letter to the hard drive to solve this issue, here are the steps, hope it still helps:
Press Win Key + R to and then type Devmgmt.msc to launch the Device Manager.
Go to Univeral Serial Bus Controller > Choose the device with an unrecognized icon.
Right-click on it and choose Uninstall.
If you still can not solve the issue, you can check this article, it lists so many ways on solving HDD not reading issue.
Have a nice day.
